I retested this on 64-bit and 32-bit and it also passes my tests.

I've pushed this to master.

I admit I hadn't noticed the misaligned_chunk vs. aligned_OK differences,
but you are correct. The tcache does operate on the memory directly (this
is because the memory is considered in-use by the thread), while the
rest of the checks should use misaligned_chunk (operate directly on chunk).

Thanks for working through this.

We'll sync Fedora Rawhide and retest (Thanks DJ!)
